Unable to take S1 Test

[Bernardo Elayda]

Hello,
I have completed the Block 1 and Block 2 training courses.  I've requested the S1 ATC test. But, when I click on the button or link given, I get this error message:

There are CBT requirements assigned with this exam have not been completed. The name of he CBT is Delivery and Ground Control.  Press OK to be taken to the CBT.

When I click on OK, it takes me to the CBT page which does how these items complete.  How do I get past this so I can take the exam?

Hi Bernardo,

Have you completed both Block 1 and 2 including the “Check for understanding” quiz?

Thk u!  I had to just retake the 'understanding' test for block 2. Now, I can take the test.
regards!
